Hello,


It doesn't sound like you have split tunneling configured correctly:  ie, when you connect, all traffic (including internet) *has* to go over the VPN, and unless you configure it properly there, it won't get sent out to the internet.


The easiest way to fix this is to only send traffic behind the VPN firewall over the VPN, and let your internet connectivity use your local connection without going over the VPN.  This is called split tunneling.  Try configuring it using the link below.

If you still have problems, try attaching the configuration of your firewall to you next message and we'll take a look at what could be happening.

Hello,


Sounds like you do not have an outside nat configuration line on the

firewall. Please try the following:


global (outside) 1 interface -- You can use the existing global


nat (outside) 1


same-security-traffic permit intra-interface


This will ensure that the internet traffic gets Hair-pinned and sent to

internet.


Hope this helps.
